Preparation of monosized spherical titania fine particles by controlled hydrolysis of titanium tetraethoxide in ethanol

Synthesis of nanosized TiO2 particles in reverse micelle systems and their photocatalytic activity for degradation of toluene in gas phase

“…Various synthesis methods including the CVD method [17], colloidal template [2], hydrolysis [18,19], sol-gel [20][21][22], microemulsion (or reverse micelle systems) [6,16,23,24] and hydrothermal synthesis [25,26], have been used to prepare TiO 2 nanoparticles. The sol-gel method [27] requires costly organic solvents.…”

Release of Volatile Compounds from Polymeric Microcapsules Mediated by Photocatalytic Nanoparticles

“…The knowledge of PZC of titania (PZC = 6.8) helps to predict the type and nature of the charge transfer that occurs preferentially. Since the photocatalytic assays were performed at pH higher than the reference PZC of titania, the surface of TiO 2 nanoparticles has a negative charge and there is an electrostatic adsorption between negative-charged surfaces of TiO 2 and methylene blue cations that carry a positive charge (2) [29][30][31]:…”

Highly polarized anatase TiO2 nanoparticles by poly(ethylene phthalate)

“…[4][5][6][7] Much research has focused on controlling the particle size and shape by employing specific techniques such as the solgel method, because it is known that particle morphology, size, distribution and porosity could enormously affect the overall properties of the particles. [8][9][10] Very recently, our group has reported that when the surface charge of the particle is changed, the particle properties also change or new characteristics are found. 11,12 For example, when the surface polarity of a silver nanoparticle was increased by electron accepters such as p-benzoquinone and ionic liquids, the surface could reversibly interact with olefin molecules, resulting in facilitated olefin transport.…”
